This paper investigates piston mode operation (PMO) when two kinds of surface acoustic wave (SAW) exist and are coupled to each other. The extended thin plate model is used for the analysis. Firstly, a PMO condition is derived in an analytical and closed form from the model. It is found that PMO is possible without adding phase shifters when two SAW modes are coupled. Then, parameters defined in the...
This paper presented a 4-bit switched-line phase shifter based on the metal-contact SPDT RF MEMS switches. The phase shift module was fabricated on a 20mil RO4350 substrate and mounted with its driver module on an Aluminum platform. This electrically tunable phase shifter is suitable for taking place of mechanical phase shifters used in base station. Measurements indicated a maximum phase shift of...
